session. (This is beneficial when a home or business owner wishes to listen-in after the central station has finished.)
The Model 1241 features a relay which can be controlled by the central station. When an Eagle Model 1400 Auxiliary
Relay Module is connected to P8, then the central station can activate the relay with a
activation is a 350 mS (350 milli-Second) pulse which energizes the relay. The Model 1400 provides DPDT

5.1 INTERNAL CONTROLS.
5.1.1 CENTRAL STATION DETECTION.
The model 1241 features Eagle's exclusive central station detection. This feature allows the audio module to detect
a central station receiver dropping off line before an operator picks up on the Two Way line. When detected (about
15 to 20 seconds post receiver hang up) the module will shut itself down and initiate the five minute call back
window.
This feature also is useful if the central station operator does not send the shut-down command. In this case the
module will shut down (after 15 to 20 seconds post operator hang up). It will not activate the call back mode.
6.0 OPTIONAL CONNECTIONS.
Several accessories can be connected to the Eagle Model 1241 providing additional features. The following
describes those accessories.
P1 - DPDT relay connection.
If the system to which the Model 1241 is connected is using an internal sounder (siren, bell or buzzer), it should be
interrupted during Two Way. This will allow the central station maximum listen-in ability without interference. These
connections may be made at either of two places. Series one lead of the sounder through terminals N.C. and N.C.
This is a normally closed relay connection which will open during Two Way. Optionally, use the 6 wire harness (P/N
117000, connected to P1) to make the connection.
